hi, i have limited tech knowledge, and usually find help through google searches, this one is not finding anything. I stupidly ran an .exe file from web (thought was a info file which i open often, didnt see the .exe) avg instantly reported 2 files were moved to quarantine. the pc was making grinding noises, so i shut down. Upon pressing the power button I get the light on the cd drive and power light come on, but screen stays black. I can press F8 and get the the boot screen, but that has no effect. I have inserted the xp disc (from old pc, this one came with it pre installed) does that matter? Upon my searches online I have tried a site which suggested: copy c:\windows\repair\system c:\windows\system32\config\system copy c:\windows\repair\system\software c:\windows\system32\config\software copy c:\windows\repair\system\sam c:\windows\system32\config\sam copy c:\windows\repair\system\security c:\windows\system32\config\security copy c:\windows\repair\system\default c:\windows\system32\config\default Nothing happened there. I am now doing a chkdsk /r That quickly reached 50% then slowed down until 70% then dropped back to 50% ??? it is no longer making noises and gone to 51% after 2 minutes. any ideas how to repair? im guessing its a boot.ini problem? a virus from the .exe? I am happy to reinstall windows, but there are pictures of my 2yr old on harddrive which i didnt get to back up to portable drive, would like to rescue them first if possible. Hope someone can help. edit: ok that chkdsk ran, and found one error, typed exit, no fix. also tried: COPY D:\i386\NTLDR C: COPY D:\i386\NTDETECT.COM C: and a fixboot again nothing, it just stays blank.
